Thanks Spanke. Mine is actually a 1975 Trillium 1300. It does seem like they are different. I took step by step pictures as I took it out. I will post them on this thread so anyone else looking can see how it's done.

So I would like to add my furnace removal on this thread since It was easy to find when I was searching for info.
Mine is a 1975 Trillium 1300 and seems different from the 4500 Trillium.

I removed the housing or face plate. ( I may not get my terms correct) There were a few screws in plain view.

so like everyone else I couldn't get the Duotherm to move more than a 1/4". I opened up the bench where the water tank is and I could kind of see the back. So some banging, pulling, jiggling, shaking it wasn't coming off.

I went outside and removed the vent.

Well the metal at the end of the vent was fastened to the housing with two self taping screws. I removed these but it still would not move. The end was larger than the hole itself.

I needed to remove this larger cap so I can push it all back into the trailer. I could pull on the furnace and it would move more than before.

There are 2 rivets on either side at the top and 1 on either side at the bottom. So I tried to use a drill but the angle was hard. I could get almost all the way through on the outside ones. I was able to take an all and punch it out because it was partially drilled out. I also put a 2x4 up against the side so there was something firm to hit against. The inside ones were a little more of a challenge but I got them out. It cam off the end rather nice.

As you can see I had to bend the top of the cap which was angled up to fit through the hole. Once I started to pull from the front of the furnace it started to move. I thought it was still hung up but with some back and forth, up and down it finally came right out.

Like everyone else I had several wasp nest in the pipe. I think when I reinstall it I may put metal screening over the vent cap. This will stop insects from getting in.

Don, Great pictures! I like your approach to removing the furnace much more then mine. I suspect that putting it back in might be kinda difficult though. It would probably help to remove the fridge so that you can get to the vent when you are re-installing it.

I think it will slide back in pretty easy. It is always easier before you actually do it.

Since it is out I am going to look at replacing all the little cover for the water hook ups and power. They are pretty brittle and this gives me full access to them.

Well I got my heater into Panda Propane today. I learnt it is a gravity fed heater and not a furnace. They no longer make these. You can't find parts for them and everyone is looking for parts. Mine looks in good shape so hopefully it just needs a good cleaning. Guess I will find out in a week. Fingers crossed.
